The first rotating shaft 55 has a worm gear 57
Is attached. The worm gear 57 has a bearing 58 at an end opposite to the planetary gear unit 46. The bearing portion 58 is provided in the gear box 5.
0 is pivotally supported by the peripheral wall on the other end side. Therefore, a shaft support 59 is formed on the peripheral wall on the other end side. Thereby, the driving force is transmitted to the first rotating shaft 55 via the planetary gear units 24 and 46 in the coaxial direction with the motor 22.

The shaft support 59 has a recess formed in the peripheral wall of the lower case body 53, the first rotating shaft 55 is dropped into this recess, and the first rotating shaft 55 dropped by the upper case body 54. Is held down.

A second rotating shaft 60 is provided in a direction orthogonal to the first rotating shaft 55. A worm wheel 61 with which the worm gear 57 meshes is attached to the second rotating shaft 60. A bearing 62 is formed on the worm wheel 61, and the bearing 62 is supported by the peripheral wall of the gear box 50. Therefore, a shaft support 63 is formed on the peripheral wall. The shaft support 63 is formed so as to protrude from the lower case body 53 at a position higher than the shaft support 59, and the protruding height is such that the worm gear 57 and the worm wheel 61 can mesh well. And height.

The shaft support 63 is formed on the peripheral wall of the gear box 50 on the side wall side.
Is supported at a position higher than the position at which it is supported.

The shaft support 63 has a recess formed in the peripheral wall on the side of the lower case body 53, the first rotary shaft 55 is dropped into the recess, and the first rotary shaft 55 is further dropped by the upper case body 54. It is configured by pressing down the rotating shaft 55.

After the first rotary shaft 55 and the second rotary shaft 60 are disposed inside, the upper cover 54 is attached and fixed to the lower cover 53 by, for example, screws. Thus, the gear box 50 is configured to protect the first rotation shaft 55 and the second rotation shaft 60.

The drive control box 20 having such a configuration is mounted and fixed to the base 70 by a fixing stay 71. The fixed stay 71 is formed in a U-shape corresponding to the outer peripheral walls of the planetary gear units 24 and 46. Then, the drive control box 20 is brought into contact with the U-shaped inner peripheral wall side, and the fixing stay 71 is fixed to the base 70 with screws or the like, so that the drive control box 20 is attached and fixed to the base 70. Is configured.

The number of the fixed stays 71 is not limited to one, but may be plural. For example, as shown in FIG.
For example, a configuration in which the fixing stay 71 is disposed on the planetary gear units 24 and 46 and fixedly attached thereto may be employed.

After attaching the fixed stay 71, FIG.
As shown in the figure, a cross crank 72 is attached to the first rotation shaft 55 and the second rotation shaft 60, and various driving mechanisms are connected to the cross crank 72, so that various movements can be performed. .

The cross crank 72 may have a configuration in which only one direction is left and other portions are cut away as shown in FIG. Further, various driving mechanisms other than the cross crank 72 may be attached to the first rotating shaft 55 and the second rotating shaft 60.

The operation of the drive control box 20 having the above configuration will be described below.

First, when assembling the drive control box 20, the planetary gear unit 24 is assembled as shown in FIG. In this case, the planetary gear member 36 is assembled. The planetary gear 28 is inserted through the planetary shaft 31 so as to be rotatably supported by the planetary shaft 31. After that, the sun gear plate 33 is inserted through the pin 34 to form the planetary gear member 36.

Thereafter, as shown in FIG. 4, the planetary gear member 36 is housed in the case body 37, the cover member 39 is further covered, and the mounting hook 40 is engaged with the engaging portion 41. A unit 24 is formed.

As shown in FIG. 5, when assembling the planetary gear unit 46, the assembly is performed in the same procedure.

After the planetary gear units 24 and 46 are assembled, a desired number of the planetary gear units 24 are joined to each other as shown in FIG. In this case, the extension hook 43 is locked to the engagement portion 44 and the planetary gear unit 2
4 is prevented from coming off.

Then, a planetary gear unit 46 is joined to one end where the planetary gear unit 24 is joined. Even when the planetary gear unit 46 is joined, the planetary gear unit 46 is also engaged with the engaging portion 44 and fixed.

When a large torque is applied to the first rotating shaft 55, twisting may occur only by connecting the planetary gear unit 24 and the planetary gear unit 46. Therefore, as shown in FIG. 7, a communication hole (not shown) communicating with all of the planetary gear units 24 and 46 is formed, and a bolt 73 is inserted into the communication hole. And after this, bolt 73
Are fixed with nuts 74, these planetary gear units 2
The connection between 4, 46 can be made strong.

Thereafter, as shown in FIG.
The planetary gear unit 24 and the motor stay 21 are joined by inserting the claw portion 25 of the motor stay 21 to which the is attached toward the engaging portion 45.

Also, as shown in FIG. 8, after attaching the first rotating shaft to the sun gear 32, the first rotating shaft 55 is supported by the lower case body 53. Then, FIG.
As shown in (1), a worm wheel 61 attached to the second rotating shaft 60 meshes with the worm gear 57, and the second rotating shaft 60 is supported by the lower case body 53.

Then, the upper case body 54 is attached and fixed to the lower case body 53, and the drive control box 20
Is formed.

Thereafter, as shown in FIG. 10, the drive control box 20 is fixed to the base 70 by fixing stays 71.
, And the cross crank 72 is inserted into the first rotary shaft 55 and the second rotary shaft 60 as shown in FIG.

Thus, the drive control box 20 can be operated while being fixed on the base 70.

When the motor 22 is operated to rotate the sun gear 23 of the motor 22, the driving force is transmitted to the planetary gear unit 24. In the planetary gear unit 24, the driving force is transmitted from the sun gear 23 to the planetary gear 28. In this case, the planetary gear 28 meshes with the peripheral gear 38 and rotates along the peripheral gear 38 at a speed lower than the rotational speed of the sun gear 23.

Then, when the planetary gear 28 moves along the peripheral wall gear 38, the plate 2 supporting the planetary gear 28
9 and the sun gear plate 33 also rotate integrally. Thus, the rotation speed of the motor 22 is reduced and the rotation drive is transmitted to the sun gear 32 formed on the sun gear plate 33.

As an example of the number of teeth of the planetary gear 28 and the sun gear 32, the number of teeth of the planetary gear is 15 and the number of teeth of the sun gear 32 is 48.
In this case, the reduction ratio is 1: 3.4.

Then, the driving force is transmitted to the sequentially laminated planetary gear units 24, the driving force is further transmitted to the planetary gear unit 46, and then the driving force is transmitted to the first rotating shaft 55. Thereby, the driving force can be transmitted to the cross crank 72 attached to the end of the first rotating shaft 55.

After the driving force is transmitted to the first rotating shaft 55, the driving force is transmitted from the worm gear 57 attached to the first rotating shaft 55 to the worm wheel 61, whereby the worm wheel 61 is attached. The driving force is transmitted to the second rotating shaft 60 that is being driven. That is, in the configuration of the present embodiment, two rotary shafts can be simultaneously driven to rotate.

As an example of the reduction ratio in this case, the speed is reduced to 20: 1 between the worm gear 57 and the worm wheel 61.

In this manner, the cross crank 72 can be driven to rotate on the second rotating shaft 60 side to perform various movements.

According to the drive control box 20 and the planetary gear units 24 and 46 having such a configuration, since the planetary gear units 24 and 46 are housed in the housing 42, the planetary gear units 24 and 46 are assembled once. Then, the work for incorporating the sun gear 32 and the planetary gear 28 becomes unnecessary thereafter. That is, when the planetary gear units 24 and 46 are joined once assembled, the planetary gear units 24 and 46 can be joined as one unit.

Since the housing 42 is composed of the case body 37 and the cover members 39 and 47, the sun gear 3
2 and the planetary gear 28 can be in an attached state in which they are securely engaged.

Further, the planetary gear unit 24 is formed with a hook 43 for replenishment and an engaging portion 44, so that the planetary gear units 24 or the planetary gear unit 24 and the planetary gear unit 46 are connected. The joining is only required to fit the extension hook 43 into the engaging portion 44, and the work becomes easy. That is, the joining of the planetary gear units 24 and 46 can be realized without attaching or removing bolts as in the related art.

Further, since the joining between the motor stay 21 and the planetary gear unit 24 can be performed only by fitting the claw 25 into the engaging portion 45, the work is simplified.

Since the first rotating shaft 55 and the second rotating shaft 60 are meshed with the gear box 50 via the worm gear 57 and the worm wheel 62, the driving force can be transmitted in two axial directions. This makes it possible to expand the range of inventiveness as a toy.

The embodiment of the present invention has been described above. However, the present invention can be variously modified. This is described below.

In the above embodiment, the case where the drive control box 20 is integrated has been described. However, as another configuration, the configuration shown in FIG. 15 can be adopted. In this configuration, the first rotation shaft 55 extends from the drive control box 20 on one side, and the drive control box 80 on the other side is formed at a position slightly separated from the drive control box 20 on one side. I have. In this configuration, the drive control box 80
Is composed of planetary gear units 24, 46 and a gear box 50.

For this reason, the driving force is taken out from the second rotating shaft 60 by the one driving control box 20, and the driving force is taken out from the first rotating shaft 55 and the second rotating shaft 60 by the other driving control box 80. If you take out the power,
The driving force is obtained from three axes.

As a result, it is possible to further expand the range of inventiveness as a toy.

By performing the same joining, a configuration in which a driving force is obtained from four or more axes can be obtained.

In addition, various modifications can be made without departing from the scope of the present invention.

[0082]

As described above, according to the planetary gear unit of the present invention, since the sun gear and the planetary gear are housed in the housing, even if the planetary gear unit is removed, the mounting state of these parts is maintained. It is possible to maintain. Therefore, if the sun gear and the planetary gear are previously attached to the housing at the time of joining, it is not necessary to attach the sun gear and the planetary gear one by one at the time of subsequent attachment.

Further, since the storage body can be locked and fixed to another storage body via a joining member and an engaging portion, when these are combined to form a drive control box, the work of joining the planetary gear units to each other is performed. Becomes easier. That is, unlike the conventional configuration, the planetary gear units are not connected to each other by screws, so that the planetary gear units can be easily joined to each other.

Further, according to the drive control box of the present invention, it is possible to easily perform the connection between the planetary gear unit, the drive source housing means and the drive force transmitting means. Further, since the driving force transmitting means includes the first rotating shaft and the second rotating shaft, the driving force can be transmitted in two axial directions.
